LOCK-HINGE.

SFECIFICATIOH' forming part of Letters Patent No. 288,345, datedNovember 13, 1883. i

To all whom itmay concern Be it known that I, JOHN A. KLINE, a citizenof the United States, residing at Boyers Ford,in the county ofMontgomery and State of l Pennsylvania, have invented a new and usefulShutter-Hinge, of which the. following is a specification, referencebeing had to the ac- Q companying drawings.

This invention relates to hinges for window blinds, shutters, and thelike, and it has for its. object to produce a lock-hinge which shall beabsolutely wind-proof, or incapable of being closed by the force of thewind against the blind or shutter which inay be hinged thereby, butwhich may be readily closed, when it shall be desired to do so, bymeans-of a simple contrivance attachcdito or forming part of the Idevice. l.

My invention therefore consists in the improved construction andarrangement of parts, which will be hereinafter fully described, andparticularly pointed out in the claim.

In the drawings hereto annexed, Figure 1 is I a perspective view,showing my improved hinge open. Fig. 21s arear view of the same. Fig. 3is aperspective view, showing the hinge in position for being closed.Fig. dis a side view, showing the hinge closed; and Fig. 5 is t a detailview, showing in perspective the several parts composing my improvedhinge deand in rear of the .pintle, is beveled, soas to form a doubleinclined track, E E.

F is a lug or stop projecting laterally from the upper end of thecylinder 0.

i G is a lug or stop projecting forwardlyfrom the upper end of thecylinder.

The leaf B of the hinge is provided with the eye L, by which it ishingeduponthe pintle D above the ring I, the upper edge of which isflush with the upper edge of the'cylinder O proper. Projecting laterallyfrom the eye L is a lug, M, which is beveled uponthe under side.

In operation, when the shutter or blind, which is attached to the leafB, is opened the leaf B will open smoothly until the lug M reaches thelug H of leaf A. The leaf B (carrying the shutter) will then be forcedslightly in an upward direction until the lug M drops down in front ofthe leaf A, where it forms a stop that prevents the leaf B from closing;At the same time the body of the leaf B reaches and abuts against thestop-lug F, preventing the said leaf B from being It will thus be seenthat the be held or retained with absolute security in an open position.In order to close the shutter it is'only necessary to turn the ring I,by means of the handle J, to the position shown in Fig. 3 of. thedrawings. By thus turning the said ring it will travel up the inclinedor beveled tracks EE, thus lifting or raising the leaf Buntil the lug Mmay pass over the upi I per edge of the lug H, thus permitting the leafB to be easily closed.

I am aware that lock-hinges have been con structed previous to myinvention comprising a beveled track for the upper leaf andsuitablestop-lugs; also, that lock-hinges have been equipped withbeveled rings interposed between the leaves for unlocking. Suchconstruction I do not, therefore, broadly claim.

I claim as myinvention and desire to secure 9 5 by Letters Patent of theUnited Statesi The combination, in a lock-hinge, of the leaf A, havingthe cylinder 0 beveled on top, so as to form the double track E E, thering I, having its under side beveled to correspond with the track E E,and provided with the my own Ihave hereto affixed my signature in arm01: handle J, the stop-111g G, projecting presence of two Witnesses.forwardly from the cylinder 0, and the leaf I B, havingthe]atera-11y-projeeting locking-111g 7 .JOHN A.
